Hydatos Moisture Locked Box logogram drop

When unlocking Moisture-Warped Lockbox, you only obtain 1 Tactical logogram as a reward. The older Heat-Warped Lockbox gave at least 4-7 Tactical logogram as a reward and thus I feel either these logograms were supposed to be Obscure (the new and extremely useful ones) or the number you get from them was inproperly applied.

World name: Coeurl

1. Obtain Moisture warped Lockbox

orrrrr the game is working as intended? just because you don't get what you think doesn't mean it's a bug.
